Mobile network operators using unlicensed spectrum

Obviously MNOs using unlicensed spectrum disadvantages others operating in that spectrum. The freedom to setup wireless networks for distinct needs without the burden of licenses for its use is an important right that has and will continue to enable innovation and advances in wireless technology. If allowed, MNOs could easily subvert that resource.
The existence of the IEEE 802.19 Wireless Coexistence Working Group to addresses coexistence between wireless standards of unlicensed devices, and in particular its Coexistence in Unlicensed Bands Study Group, is late but welcome. Perhaps equipment working in the unlicensed spectrum will ultimately be required to conform to a coexistence protocol that can be mandated by the ETSI et al. Although and extra burden on those developing for unlicensed frequencies it would ultimately be a benefit as we move to higher utilisation.
